To find the additive inverse of a number, we change its sign.
The additive inverse of -856 is 856 and the additive inverse of -1223 is 1223.
So, to find -1223 - (-856), we can rewrite the expression as 1223 + 856.
Then we can add the two numbers:
1223
+ 856
-----
2079
Therefore, -1223 - (-856) is equal to 2079.
The answer as a mixed number would be 2079.
Use the additive inverse to find −1223−(−856)
. Write the answer as a mixed number.(1 point)
